MARTIN KENNEDY, OF CHICAGO, ILLINOIS.

Specification forming part of Letters Patent No. 119,618, dated October3, 1871.

To all whom it may concern:

Be it known that I, MARTIN KENNEDY, of Ohicago, in the county of Cookand State of Illinois, have invented certain Improvements in OombinedPlow and Stock for Cultivators, of which the following is aspecification:

Figure 1 is an elevation of the stock and plow, looking toward theland-side. Fig. 2 is a side elevation of the mold-board. Fig. 3 is a topview of the stock and cultivator, and Fig. 4 is a perspective view ofone of the mold-boards that form the double plow.

This invention relates principally to a stock so constructed as toreceive different implements, such as a share and mold-board for asingle plow; two mold-boards, one on each side, both constituting adouble plow; two beams armed with shovels, and constituting acultivator; and a point, to be used when the double mold-board andcultivators are employed.

Referring to the drawing, the stock, Figures 1 and 3, is seen to consistof a solid plate, a, having cast with it at its front edge a doubleflange, b, the same being chamfered at each side so as to form a sharpridge, 0. A land-side, d, is permanently bolted to the plate a. At oneside of the stock an angular space is formed between the front end ofthe land-side d and the lower end of the double flange 12, into whichspace fits the land-side f of the single mold-board g, Figs. 1 and 2,when said mold-board is fastened to the stock a, which is done bypassing a bolt, f, through the land-side f and through the point a ofthe stock a, by the side of which point said land-side fits. Thisfastening is aided by passing the brace h of the mold-board g throughthe socket t at the rear end of the stock a, and also by means of aflange, j, cast upon the front end of the moldboard 9, and standing offtherefrom at such an angle as fits the chamfered sides of the flange b.The land-sidefof the mold-board g coincides with the land-side d, andthe outer straight side of the flange j is flush with the adjacentstraight side of the flange b. The land-side f has a sole, k, cast withit, which fits under the point a and in that position is flush with thebottom of the land-side d. When the mold-board g is attached by thesevarious means to the stock a it forms therewith a good and practicablesingle plow.

a a point, I, with a flat bottom and a socket, l,

is attached to the point a by means of a bolt,-

the point to entering the socket l, as shown in Fig. 3. The bottom ofthe point Z is flush with that of the land-side d. If it is desired tomake up a cultivator, add the beams m, Fig. 3. These beams are providedwith shovels n, and at their inner ends they have forks 0, one above theother, with holes made through them vertically. These forks are slippedover lugs 19, which have holes made through them. Pins q, passed throughboth the forks and lugs, connect the beams m with the stock a. The beamsm are provided with braces h similar in construction and operation tothe braces it. There is a pair of the lugs 19 on each side of the stocka, and when it is desired to make up a double plow two singlemold-boards, s, Fig. 4, are attached to the stock by means of bolts tpassed through lugs u projecting from the inner sides of the mold-boardss, and also through the lugs 9. Braces 1L2, passed through the sockett', aid the lugs 19 a in holding the mold-boards s in place. Cast withthe stock a, and standing out from each side thereof just above thesocket c, are two sockets, 1', which receive the ends of the handles 0:.From the inner sides of the sockets 7' bars w extend upward, incliningbackward, and flaring outward to the same degree as the handles, forwhich these bars serve as supports, the handles being fastened to themby a bolt, 00, having nuts at its ends and passing through both handlesand bars.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. The stock a, constructed with the double chamfered flange I), pointa, sockets a, and lugs 19, whereby it is adapted for the attachment ofvarious implements necessary to the performance of different functions,as shown and described.

2. In combination with the stock A, provided with the double chamferedflange b or beveled ridge 0, the mold-board 9, provided with thecorresponding flange as specified.
